grub2 compilation error on CentOS 4.2

grub2 compilation error on CentOS 4.2

[Nickolai Zeldovich]

I was trying to compile today's grub2 CVS version, and ran into the
following problem:

host% gmake
gcc [...] -c -o grub_emu-normal_lexer.o normal/lexer.c
normal/lexer.c: In function `grub_script_yylex':
normal/lexer.c:89: error: called object is not a function
normal/lexer.c:90: error: syntax error before "return"
normal/lexer.c:92: error: called object is not a function
normal/lexer.c:93: error: syntax error before '{' token

This appears to be due to a rather unfortunate preprocessor macro in
grub_script.tab.h:

host% grep define.if grub_script.tab.h
#define if 258

I'm not sure what's going on, but my version of yacc is generating
that output from grub2/normal/parser.y.

host% rpm -qf /usr/bin/yacc
byacc-1.9-28

-- kolya

Thanks for your report!

You have to use bison.  The autoconf test yet has to be changed to
enforce that.

berkley yacc doesn't work.
use bison.
configure.ac should be changed to enforce use of bison imho.
